Title: Improvements in or relating to telephone systems
Inventor: MANN VICTOR EDMUND
IPC: H04M15/04
Filed: 1958-11-20
Abstract: 906,155. Binary counting arrangements. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Nov. 17, 1959 [Nov. 20, 1958], No. 37408/58. Class 106 (1). [Also in Group XXXIX] A magnetic drum, on which an exchange operator records information relating to highvalued telephone calls, has a track which keeps count of the exchange 6 second pulses to a total of 24 hours. The track has 15 storage elements divided into blocks TBC1, TBC2, TBC3, and each having elements TA (1-5). The first four elements TA (1-4) of TBC1 count the 6-second pulses, i.e. tenths of a minute, and at every tenth pulse add one to the remaining eleven elements which count the minutes to a total of 1440, i.e. 24 hours, at which point the counter is set back to zero. The contents of the track are read into a five-stage stepping register comprised by the transistor bi-stable toggle circuits MD to MD5, Fig. 4, from a reading head which is set five elements in advance so that the contents of the track are to this extent staticized to detect a count of ten in the tenths section and a count of 1440 in the minutes section. Toggle circuits M7 to M9 of Fig. 5 control the track, the six second pulses PAC operating M7 which marks the write 0 lead SA to reverse all 1 registrations in the tenths section until a 0 is read (as appearing from the state of toggle MD5) whereupon 1 is written and M7 is reset. Toggle M8 operates in response to M7 to ensure that M7 responds once only to each PAC pulse which will extend over more than one cycle of the drum. When the PAC pulse expires M8 is reset to give further access to M7. When the tenths section records 9, MD2 and MD5 register 1 and cause M9 to operate and M7 to restore so that the process of addition is cut off when the first 1 is erased from element TA1 of block TBC1, the 1 in the element TA4 of which is erased by M9 at which time M9 is reset and M7 reoperated. With M7 operated at this time the registrations in elements TA5 of TBC1 and onward through TBC2 and TBC3 of the minutes section are reversed until a 0 is read out, as indicated by MD5, and the minutes count is thereby increased by one. When the minutes count reaches 1440 the first six elements are read out at the time TA5 of block TBC2 to produce a 1 from this element giving pulse SLR and finding toggles MD5, MD3 and MD2, with 1 registrations. This combination erases the 1 in element TA5 of TBC2 and operates M9 to erase the remaining elements, M9 being restored at element TA5 of TBC3 and leaving the minutes section bare. Specification 888,145 is referred to.

Title: Apparatus for indicating and regulating the temperature and the heat content of liquid in a container
IPC: G01K3/06
Filed: 1964-09-14
Abstract: 1,077,589. Automatic temperature control. SIEMENS - ELECTROGE RATE G.m.b.H. Sept. 14, 1964 [Sept. 18, 1963], No. 37534/64. Heading G3R. [Also in Division G1] The maximum and mean temperatures in a hot water container 1, Fig. 1, are measured respectively by a sensing element 16, and a chain of sensing elements 15, and are indicated on the same scale of an instrument (20) Fig.2 (not shown) by a moving vane (23) and a pointer (22) respectively. A required temperature is preset at 8, Fig. 1, by a knob (25) Fig. 2 (not shown) on the front of the instrument (20), and a heater 6 is operated in accordance with the temperature measured by a further sensing element 9, which may be a liquid expansion type. The sensing elements 15, 16 may be semi-conductor devices, thermistors, or liquid expansion type. The heater 6 may alternatively be controlled from the indicator itself by replacing the vane (23) and pointer (22) by two pointers (23, 22) Fig.3  (not shown) each having a contact (28, 27) which can engage a corresponding contact (31, 30) on a movable vane (29). The contacts (28, 31) are initially closed and the heater operates so that the maximum temperature pointer (23) and the mean temperature pointer (22) together move over the scale, the vane (29) following under spring pressure until the vane reaches a preset position, when the contacts (28, 31) open and turn off the heater. The heater is turned on again when the mean temperature pointer (22) falls far enough to close contacts (27, 30). The indicator pointers may be operated by moving coil instruments, by bi-metallic strips heated by a current depending on the resistance of the sensing elements 15, 16, or mechanically by liquid expansion type sensing elements. The indicator may take the form, alternatively, of glow tubes, or of a linear or drum-type scale.

Title: Gas turbine engine fuel control system
IPC: F02C9/32
Filed: 1974-11-06
Abstract: 1494615 Automatic control of gas turbine engines LUCAS INDUSTRIES Ltd 6 Nov 1974 [10 Aug 1973] 37916/73 Heading G3N An acceleration fuel limit signal is provided in the fuel control system for a gas turbine engine by means responsive to the speed of air-flow in the engine compressor and the engine rotary speed. In the arrangement shown, the engine speed N and  compressor inlet temperature T1 are combined in a function generator 13 to provide a signal corresponding to the maximum speed of gas flow. The actual speed of gas flow is detected by a doppler type gas velocity transducer and is compared with the maximum speed signal in comparator 14 to produce an acceleration fuel limit signal. The control logic circuit provides a normal fuel control signal to the fuel system 11 but this may be overridden by the limit signal from comparator 14 when necessary. The arrangement reduces the possibility of the compressor stalling during acceleration.

Title: Free piston engine
IPC: F02B71/02
Filed: 1971-08-18
Abstract: 1357957 Free piston engines A BRAUN 18 Aug 1971 [24 Aug 1970] 38808/71 Heading F1B A free piston engine comprises sensing means arranged to generate an electric signal at an instant and with a magnitude dependent upon a characteristic of the movement (as distinct from position) of the piston and an electrical control circuit controlling operation of the means (e.g. spark-plug and/or fuel injection pump) for causing combustion. The piston velocity of the engine is sensed by a stationary coil 28, Fig. 2, traversed by a permanent magnet carried by the piston-rod. An adjustable proportion of the voltage generated in the coil 28 is applied via a potentiometer 34, 38 to a Schmitt trigger 83. During the compression stroke, the passage of the magnet past the coil 28 generates a voltage which switches on the Schmitt trigger, thereby producing a negative step in the collector voltage of a following amplifier 88. The resultant negative pulse transmitted by a capacitor 96 is suppressed by a diode 100. Near the end of the stroke, the reduction of piston velocity causes the generated voltage to decrease to a value at which the Schmitt trigger is switched off. The resultant positive pulse transmitted by the capacitor 96 triggers a thyristor 112 into conduction in a capacitor-discharge ignition circuit to provide spark ignition. Adjustment of ignition timing is effected by variable resistor 34. During starting, when the piston velocity is insufficient to generate a high enough voltage to operate the Schmitt trigger, operation of the latter may be effected by the circuit modification shown in Fig. 7. A stationary reed switch 136, closed during a portion of each stroke by a magnet moving with the piston discharges a capacitor 134 through the base of a transistor 60 having its emitter and collector connected in parallel with those of the first transistor 50 of the Schmitt trigger 83, thereby switching on the Schmitt trigger. When the switch 136 is switched off, the capacitor 134 re-charges through a resistor. At normal engine speed, there is insufficient time during each stroke to charge the capacitor 134 to a high enough voltage to operate the Schmitt trigger, which reverts to normal operation. As a further aid to starting, the resistor 38, Fig. 2, may be of a high enough value to provide sufficient voltage at starting to operate the Schmitt trigger, another resistor (166), Fig. 13 (not shown), being switched into parallel with the resistor 38 during normal running to provide the normal voltage, this switching being effected by a transistor (162) in series with the resistor (166) and rendered conductive by a voltage applied to its base, this voltage being generated by the engine and having the required amplitude only at normal running speed. In a further modification, a resistancecapacitance network and a diode are connected in series with the coil 28, whereby a negative bias is built up during normal running to reduce the net voltage available for operating the Schmitt trigger, the full voltage generated in the coil being available at starting.

Abstract: 1,235,476. Edge veneering. ENGLISH ROSE KITCHENS Ltd. 25 Nov., 1968 [23 Aug., 1967], No. 38814/67. Heading B6L. A machine for securing an edge veneer to one or both edge faces of a panel comprises a conveyer 9, 10 adapted to carry and locate panels bearing veneer strips to be secured by catalytically activated bonding adhesive, a pair of opposed elongated clamping members 62, 63 disposed along opposite edges of the conveyer and relatively movable towards and away from each other, at least one of said clamping members including heating means, control means adapted to produce intermittent feed movement of the conveyer, and means controlling the relative movement of the clamping members in phase with the movement of the conveyer so that the clamping members remain in an open condition during movement of the conveyer and are caused to close to grip the panel edges and apply heat thereto to cure or set the adhesive and so bond the veneer to the panel edge(s) when the conveyer comes to rest. In the machine described panels are advanced intermittently by the conveyer 9, 10 past devices 25 which apply glue to the opposite panel edges. Edge veneer strips from magazines 38 are advanced by reciprocating feed devices into the path of the panels and are pressed against the panel edges by rollers 60 as the panel is advanced. A liquid catalyst or hardener agent for the adhesive is applied to the veneer strips before they contact the adhesive-coated panel edges. The panel with the veneer strips attached comes to rest between the clamping members 62, 63, one of which is then advanced under the action of pneumatic cylinders 70 to grip the panel. Simultaneously heat is supplied to the panel edges by electric resistance elements in the members 62, 63 to cure or set the adhesive. After a given time the member 62 is withdrawn and the panel is advanced out of the machine, and may be fed to a veneer trimming machine as disclosed in Specification 1,235,477. The panel may be of wood or wood composite, e.g. chipboard, the veneers of wood, or plastics laminate or sheet, and the adhesive may be a urea-formaldehyde resin. The member 63 and the conveyer chain 10 may be adjustable relative to the machine frame to cater for panels of different sizes.
